[A new idea on organizing our knowledge-base]: Infographic and Questions

Before, I wrote an entry about a way to organise our knowledge-base. Today, I continue to clarify my point thru an infographic, and suggest some deeper questions to perfect this idea.

The Venn diagram above perfectly expresses my thought on this issue, with 3 key words: context, idea, and connection. So, for each idea, or information, we should define its belonging context and its connected partners. It will help us to retrieve information more concise and fast. Here, there are some critical questions when we apply it in real.
1) How to define a good context? I think a context should be a real-world usage situation, such as greeting, asking health, shopping, etc... Therefore, basically, a context is also an general/abstract essential vocabulary.
2) How to define a connection? Obviously, an idea somehow links to others in the same context, then, such connections should be considered as implicit one. An explicit connection should connect 2 ideas that is directly relate or involve to each other in meaning.
